Improvement in brick-machines



UNITED STATES PATENT OFFICE.

W. A. HORRALL, OF WASHINGTON, INDIANA, ASSIGNOR TO HIMSELF AND ALBERT W. CROSS, OF SAME PLACE.

IMPROVEMENT IN BRICK-MACHINES.

Specification forming part of Letters Patent No. 46, l 88, dated January 31, 1866.

To aZZ whom it may concern:

Be it known that l, W. A. HORRALL, (f Washington, in the county of Davies a1 d State of Indiana, have invented a new and Improved Brick'Machine; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a side sectional view of my invention, taken in the line as m, Fig. 2; Fig. 2, a horizontal section of the same, taken in the line y y, Fig.1.

Similar letters of reference indicate corresponding parts in the two figures.

This invention relates to a new and improved machine for pressing and molding bricks; and it consists in the employment or use of a mudmill, a pressure-roller, clay-box, and an endless band, all arranged in such a manner as to admit of the work being very expeditiously performed and in a thorough manner.

To enable those skilled in the art to fully understand and construct my invention, 1 will proceed to describe it.

A represents a framing in which an upright box, B, is placed, and U is a vertical shaft which passes centrally through the box B and has its bearings in the framing A. The shaft 0 has a series of horizontal arms, a, attached to it, which are within the box B, and at one side of said box, at its lower end, there is an opening, b, the bottom of which should be flush with or a little below the bottom of the box B.

D is a box which is secured to the framing A directly below the opening I). This box D is not provided with a bottom, and it is directly over two horizontal parallel side pieces, E E, which are connected near their-ends by bottom pieces, 0 c.

F is an endless band which works over rollers d d, fitted between the lower parts of the side pieces, E E. This band extends about half-way underneath the box D, and the former has plates, 0 attached to it at suitable distances apart to admit of the molds G being inserted between them. The band F is enabled to support the molds by means of a series of rollers, H, around which the belt works, as shown in Fig. 1.

Within the box D there is placed a roller, I, which is over the space he; ond the endless band F and below the box D; at its end beyond the endless hand there is a roller, J, the journals of which are in the side pieces, E E.

Motion is communicated to the endless band F by means of bevel-gears f, one of which is at the lower end of the shaft 0 and the other on the journal of the roller 01 of said band.

The operation is as follows: The shaft 0 is rotated by any convenient power, and the clay properly moistened is thrown into the box B, the arms a on O tempering and grinding the clay and discharging the lower tempered and ground portion through the opening 1) into the box D. The endless band F is moved in the direction indicated by arrow 1, and conveys the molds G underneath the box D and roller 1, the latter pressing the clay into the molds, as shown clearly in Fig. 1. The roller I is rotated by gearing g from the roller (1.

The whole arrangement is exceedingly simple, and the device operates very smoothly, it not having any of those jars and concussions which attend the presses having a reciprocatin g mold-discharging device.

Having thusdescribed my invention, what I claim as new, and desire to secure by Letters Patent, is-

So connecting the mechanism which drives the molds to the gear-wl1eel 011 the pressureroller-shaftthat the mold and periphery of the pressure-roller shall move in exact unison, byv

which their passage is facilitated and the clay evenly pressed, substantially as herein de- Witnesses:
